Burrell and Stonestreet face off against Alec Baldwin, who has never lost the category; this could be his sixth consecutive victory for playing Jack Donaghy on “30 Rock,” which received two other nominations this year: Comedy Ensemble and Comedy Actress (Tina Fey).

Steve Carell, who departed “The Office” last spring, received a pair of farewell bids for Comedy Ensemble and Comedy Actor; he has won twice as a member of the “Office” ensemble, but has never claimed individual honors. At this year’s Emmys, he was upset by Jim Parsons, who won his second consecutive trophy for “The Big Bang Theory,” but Parsons has never been embraced by SAG, and this year is no exception; though “Big Bang” broke through for the first time in the Comedy Ensemble race, Parsons was left out of the Comedy Actor lineup.

The last Comedy Actor contender is Jon Cryer, a surprise nominee for “Two and a Half Men“; he’s been nominated for six Emmys winning once, but this is his first nomination from the Guild. Is it possible sympathy for the Charlie Sheen controversy pushed him over the top?

Last year’s Drama Ensemble champ “Boardwalk Empire” won’t be facing off against Emmy victor “Mad Men,” which didn’t air any new episodes this year. “Breaking Bad,” “Dexter,” “Game of Thrones,” and “The Good Wife” are all looking for their first win in the category. “Thrones” and “Bad” are nominated for the first time, while “Good Wife” makes its third appearance and “Dexter” its fourth.
